In addition to microturbine generators, what other types of power devices could be used to produce a hybrid fuel cell system?
Hybrid systems that include combinations of fuel cells with power production, power storage, energy conversion, or energy management devices are extremely promising. Heat engines, like microturbine generators, reciprocating or stirling engines, could run using a fuel cell’s waste heat to produce additional electricity and/or pressurize the fuel cell. Batteries and flywheels could be used to store power and then feed it back to the system when energy demand becomes high. Fuel cells can even be joined to other fuel cells for hydrogen production and chemical energy storage.
